Becaue the icing sugar has small paricles.
Only sugar is soluble in water.
The icing sugar has a greater surface area than the lump and so the reaction occurs more easily with the icing sugar powder. This in general applies to many salts and soluble compounds.
i think its because caster sugar has smaller particles!!:)
Caster sugar or icing sugar. Sugar with larger grains do not dissolve properley in the cake mix.
It has more surface area.
If u wanted to make icing then icing sugar is better to be used. But if only sugar is available then you must melt it down in a saucepan.. Search it on google for how to do it as I'm not completely sure. I Just use icing sugar
Although it will still be edible, icing sugar will start to dry and crack after a few months.
Confectioner's sugar is icing sugar mixture (pure icing sugar with a small amount (about 3%) of starch added as an anti-caking agent). Pure icing sugar is very fine powdered refined sugar with no added starch.
If you are making icing, yes. If you are making a meringue, no.
Yes..... powdered sugar, confectioner sugar , icing sugar. Add water or juice and flavoring voila= icing
Not really; sugars other than powdered do not dissolve when used in a mixture that is not heated (such as icing). If the recipe already involves brown sugar, you can increase the quantity slightly without too many side-effects. However replacing powdered sugar (completely) with brown is likely to yield undesirable results; powdered sugar helps add 'smoothness' to icing, so without this you may end up with a very brown granular icing (that may not set adequately). If the recipe does not call for brown sugar at all, definitely do not add it.
i dont understand what you mean by pure.. but yes, you can make icing sugar
